GLOBE-VALVE.

SPECIFICATION forming part of Letters Patent No. 761,849, dated June 7, 1904.

Application filed June 27, 1903. Serial No. 163,299. (No model.)

a citizen of the United States, residing at Cathlamet, in the county of Wahkikum and State of Washington, have invented certain new and useful Improvements in Globe-Valves, of

which, the following is a specificationfrefers ence being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in globe-valves. These improvements relate to the entire valve and all its parts and include principally the construction of the body, the disk, and means for operating and grinding it, and .other'details, which I shall hereinafter fully describe.

The object of the invention is toprovide an effective and quick-acting compressionvalve' with means operated external of the body for'regrinding the disk upon its seat, and each of the improvements which I have made has in view this general result.

Theaccompanying drawing shows in vertical section a valve involving my invention.

The letter A indicates the body provided with inlet and outlet openings at and a, re spectively, which -in the drawing are represented in the same straight line, and it has, like other valves of this class, a partition 6, provided with an opening Z), which may be closed by a disk or frustum-shaped valve- C, fitting against a corresponding seat 0 of the partition. The disk is fixedly mounted upon a spindle D, which extends through stuffingbox E of the body and F of a bonnet Gr, screwed into the body opposite the valveseat.

H is a wheel fixedly secured to one end of the spindle, whereby the disk may be turned when being reground. The opposite part of the spindle passes through a sleeve I and beyond which it is screw-threaded for the reception of' jam-nuts (Z. The cylindrical surface of the said sleeve is also screw-threaded to register with screw-threads of an aperture 7:: of a bridge-piece or standard K, fastened to the body. Secured to the said sleeve is a bridge-piece L, spanning the end of the spindle and the said jam nuts, and extending through the cross-piece Z of the part L is an adjustment-screw M, adapted to be screwed against the end of the spindle and which, with the aforesaid jam-nuts, regulate the amount of movement of the spindle, and consequently the opening of the valve.

' N is a lever-handle having a bifurcated socket n, which is clamped about a hub 2' of the sleeve 1.

The operation of the invention is as follows: To open or close the'valve, the sleeve I is partially rotated by means of the handle N, which raises or lowers the sleeve through the action of the screw-threads thereon and coincidently the spindle by reason of the jam-nuts (Z and the set-screw M bearing, respectively, against the tops of the sleeve and spindle, which, as

before described, is fixedly connected to the valve. The valve is ground by first seating the same as above described, when by a few turns of the wheel the valve is caused to rub against its seat and make a tight fit therewith.

The advantages and application of the invention will be apparent from theforegoing brief description; but it may be said that it is particularly useful to control fluids under high pressure.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is v 1. In a device of the class described, the combination with the body, the valve, and its seat, of a spindle fixedly connected to said valve and extending through opposite sides of the body, means to rotate said valve without imparting any axial movement thereto, and the means to open and close said valve without rotating the same, such last-mentioned means consisting of a sleeve loosely mounted upon the valve-spindle and provided with an external screw-thread, a nut for said sleeve-screw fixedly secured to the body, and adjustable means for preventing the sleeve moving longitudinally of the spindle, substantially as and for the purposes described.

2. The herein-described valve, comprising a body, having inlet and outlet openings, a valve-seat positioned in a partition integral with the body, a spindle passed through oppositely-disposed stuffing-boxes of the body and its bonnet respectively and having one of its ends screw-threaded and a wheel upon its cured to the said sleeve and spanning the end other end, adisk valve fixedly mounted on the spindle and adapted to register with the said seat, a cylindrical sleeve loosely fitted upon the spindle contiguous to the said screwthreads and being provided with a screwthread upon its peripheral surface and registering with an inside screw-thread of a standard secured to the body, a handle for said sleeve, said standard, jam-nuts for the threaded end of said spindle, another standard seof the spindle, and a set screw extended through the last-named standard and adaplml to bear against the end of the spindle, suhstan- 5 tially as and for the purposes specified.

In testimony whereof I afiix my signature in presence of two witnesses.
